Abstract
A journal bearing comprises one or two sets of rotary bodies, i.e. rollers and/or balls, guided in a cage structure of resilient resinous material with two axially spaced annular flanges snap-fitted into respective grooves of triangular cross-section which are formed in an outer and/or an inner race. The cage structure may comprise a single annular cage with apertures receiving the rotary bodies, a pair of such cages, or two axially spaced crenelated rings. Upon engagement of the two flanges in their grooves, the cage structure, race or races and rotary bodies form a unitary assembly.
Claims12
A journal bearing comprising:
- an array of rotary bodies centered on an axis;
- annular race means forming a track in contact with said bodies, said race means having two axially spaced annular surface zones coaxial with said array on opposite sides of said track, said zones being provided with respective recesses centered on said axis;
- and
- cage means engaging said bodies for maintaining same at predetermined peripheral distances from one another, said cage means having a pair of axially opposite end faces peripherally bounded by radially projecting resilient formations snap-fitted into said recesses, said cage means and race means together consisting of at least three interfitting coaxial members carrying said formations and recesses for enabling independent interengagement of said formations with said recesses to form a coherent unit with said bodies.
